    tutorial says it all but i can give a tip. If you think you are going to solve a problem with dp check limits for variables. Like if N<=2000 you will probably have 2 dimensions with size of N. Because usually memory limit is about 128 or 256 MB and you cant have an integer array sized bigger than 10^7. So you can guess dimensions of dp. Then build the logic.
